To prevent small fish, Invertebrates, etc from being lodged in the Overflow Boxes, they have been equipped with slotted teeth on 3 sides. The 6" x 6" x 6" Overflow Box has been designed with the Safety Overflow System (S.O.S.) to ensure a continuous siphon at all times. The Trapezoid configuration is designed to be slim and fit in narrow aquariums allowing maximum surface skimming.
